DISPENSER.

To all whom it may concern:

Beit known that I, EDMUND Brennan, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dispensers, of which the following is a specification.

This invention relates to improvements in devices for dispensing plastic substances, as, for example, grit soap, soap paste and the like.

In the accompanying drawings, Figure 1 is a side elevation of a dispenser embodying the features of my invention. Fig. 2 is a vertical sectional view taken in the plane of dotted line 2 of Fig. 1. Fig. 3 is a top plan view. Fig. 4 is a sectional view taken approximately in the plane of dotted line 44L of Fig. 2. Fig. 5 is a section on line 5-5 of Fig. 2. Fig. 6 is a section on line 6-6 of Fig. 2. Fig. 7 is a section on line 6-6 of Fig. 2, but looking upward. Fig. 8 is a {rag mental vertical sectional view. Fig. 9 is a view illustrating a lock'ior the casing. Fig. 10 is a lower side view of a disk comprised in the dispenser. Fig. 11 is a top plan view oi": a container adapted for use with the dispenser.

While the dispenser may be located and supported in any suitable way, it is'herein shown as comprising a bracket adapted to be attached to the wall. A bracket of any preferred form and construction may be employed. The one herein shown comprises a base 1 formed integral with a frame that sup ports the container and the extruding mechanism. The frame consists oi a rear post 2 and a front post 3, the upper ends of said posts being connected by a disk 4, and the lower ends thereof being united by a disk 5.

The soap or other material to be dispensed is contained in a can 6, the body of which is cylindrical. The lower end of the can has a discharge opening of any desired form; herein is shown an elongated opening 7 (Fig. 11). At the upper end of the can is an inwardly extending annular flange 8 (Figs. 2'and 11). Within the can is a floating head 9 having an annular guide flange 10 that slides in contact with the cylindrical wall of the can. The can is supported within acasingll carried by the before-mentioned frame. The means for forcing the head 9 downwardly to extrude the soap through the outlet 7 includes Specification of Letters Patent.

an internally-threaded sleeve 12. Said casmg and sleeve are rigldly connected together and are severed to form two vertical halves which are pivoted to the frame so that they may be swung apart to permit the insertion and removal otcans and the restoration of the extruding mechanism to initial position. As best shown in Figs. 1 and 3, the two halves or sections are pivoted upon a pintle 13 fixed in the frame, and the two sections'oif the easing, being rigid with the sleeve sections, swing therewith. To permit of the relative swinging movement of the casing sections, they are cut away at their adjoining rear edges (Fig. The sections may be locked in closed position byany suitable means, as, for example, a hook l l pivoted at 15 on one section oi the sleeve 12 and engaging a stud 16 on the other section. A coiled ex pansion spring 17 normally holds the hook 14: against a stop lug 18. The free end 01 the hook is beveled so as to be raised by the stud 16 when the sections of the sleeve are swung together. 19 is a housing, formed one-half on each section of the sleeve 12, for enclosing the lock. The hook may be pushed up out of engagement with the stud 16 by means of an implement inserted through a hole 20 in the bottom wall of the housing.

Each section ofthe casing 11 comprises an inwardly extending flange or ledge 21 (Fig. 2) on which the can 6 rests. in Figs. 1 and 2, the casing 11 is provided with openings 22 through which labels or the like on the can may be seen. In order to pre vent the can from being inserted into the casing in such position that the labels do not register with said openings, 1 place two pins 23 (Fig. 10) upon the lower side of the disk 5, which pins are not diametrically opposite each other. In the flange 8 of the can are formed two openings 24 (Fig. 11) to receive the pins 23.

.The means for forcing the head 9 downwardly within the can comprises a plunger consisting of a disk 25 bearing against the head 9 and rigidly secured to a tubular stem 26. Said stem is slidable'through an opening 27 in the head 5. The upper end of the stem 26 is connected to a member having a screw-thread connection with the sleeve 12. The upper portion of the stem 26 is rigidly secured to a disk 28 having a loose connection with an externally-threaded member 29 As shown j .the member 29 and in recesses 36 the balls 34, thus that engages the internally-threaded sleeve 12. Separating movement of. the disk 28 from the member 29 is turned flange 30 on the stem 26, said stem extending slidably through a central opening in the member 29. The loose connection between the disk 28 and the member 29 consists of a lug 31 on the upper side of the disk 28, which lug lies Within an elongated recess 32 in the lower side of the member 29. When the member 29 is turned in the direction to cause said member to move downwardly in the sleeve 12, the end wall 33 of the recess 32 engages the lug 31 and causes the die; 28

also to turn.

The contents of the can being slightly compressible and expansible, extrusion of the soap would-continue for a few moments after downward. movement of the member 29 had ceased, 1f means were not provided to prevent such action. For this purpose, I have provided plurality of balls 34 (Fig. 6) lying'in sockets 35 in the lower side of in the upper side of the disk 28. The recesses 36 are deeper at one end than at the other, so that as the balls 34 roll up the sloping bottom walls of said recesses, the disk 28 is forced away from the member 29. Contact between the lug 31 and the end wall of the recess 32 limits relative turning move ment of the parts 28 and 29. When clown- Ward movement of the member 29 stops, expansion of the contents of the can causes the disk 28 to turn in the direction to bring the deep end of the recesses 36 into register with.

causing the disk 28 to approach the member 29. The pressure of the soap thus expends itself in moving the disk 28 insteadof in forcing soap through the outlet 7.

The means for rotating the member 29 comprises a finger lever 37 fixed upon a shaft 38 which is rotatably mounted in the disk 4. The lever 37'. extends through a slot 39 in the enlarged upper end of the sleeve A coiled tension spring 40 secured at one end to the frame and at its other end to an arm of the lever 37 normally holds said lever against an end wall of the slot 39.

The shaft 38 is square in cross-section throughout most of its length. It-extends into the tubular stem 26, being cylindrical at its lower end to keep it central in the stem.

lVithin the member 29 is rotatably mount-- ed a pawl-carrier 41 having, in this instance, the form of a disk. Said disk has a square central opening through which the shaft 38 extends slidably, whereby the disk is caused to turn with the shaft. 42 is a circular cover plate secured to the member 29 and overlying the disk 41. Said disk carries a suitable number of pawls 43 which, are slidably mounted in guidoways in the disk, Expanlimited by an out-- upper end of the sion springs hold the teeth of the pawls against an annular series of interval ratchet teeth 45 formed in the member 29. p

In use, the operator reeiprocates the "lever 37 one or more times, thus turning the square shaft 38 and the pawl-carrier 41, the pawls 43 causing the member 29 to turn in the direction to travel downwardly in the sleeve 12. As the member 29 turns, the balls 34, acting against the sloping walls of the recesses 36, crowd the disk 28 down until the end wall 33 of the recess 32 strikes the lug 31, after which further rotation of the member 29 causes the disk 28 to turn. The downward movement of the parts 28 and 29 causes the head 9 to descend in the can, whereby soap is forced out of the open ing 7. When the operator ceases operation of the lever 37, the pressure of the sloping bottom walls of the recesses 36 against the balls 34, due to the pressure of the contents of the can, causes the disk 28 to turn to bring the deepest portions of said recesses into register with the balls,'in which movement the disk 28 approaches the member 29. The pressure on the contents of the can is thus relieved, and the flowof soap through the opening 7 ceases.

When the can 6 is empty, the casing 11 and sleeve 12 are opened, thus disengaging thesleeve from the member 29. The operator may then grasp the member'29 and raise it and the disk 25 until the container 6 can be slid off the ledges 21. A fresh can is then set in place, with the disk25 resting upon the head 9 of such can, 11 and sleeve 12 closed.
